Detective Mara Quinn arrived at Blackwood Manor precisely at midnight while rain hammered ancient shutters violently overhead without mercy tonight. Butler opened door silently, eyes avoiding hallway where Lord Ashford lay sprawled unnaturally beneath shattered crystal chandelier gleaming ominously still. Blood pooled darkly across priceless Persian rug, yet no footprints disturbed surrounding dust despite apparent violent struggle inside locked library. Quinn crouched low, noticing victim's clenched fist concealed crumpled ivory invitation dated tomorrow night bearing her own handwritten name clearly. Behind her, someone whispered that Ashford had predicted his murder exactly one week earlier during dinner party guests never forgot.
